Controlled assembly of gold nanoparticles and graphene oxide sheets on dip pen nanolithography-generated templates by Li, Bing, Lu, Gang, Boey, Freddy Yin Chiang, Zhou, Xiaozhu, Cao, Xiehong, Zhang, Hua

“…The templates were obtained by passivation of the exposed Au area with AUT after 16-mercaptohexadecanoic acid (MHA) patterns were generated by dip-pen nanolithography (DPN) on Au. The electrostatic interaction ensures that the Au NPs and GO sheets only adsorb on the designed AUT areas. …”

Patterning colloidal metal nanoparticles for controlled growth of carbon nanotubes by Li, Bing, Goh, Chin Foo, Zhou, Xiaozhu, Lu, Gang, Tantang, Hosea, Chen, Yanhong, Xue, Can, Zhang, Hua, Boey, Freddy Yin Chiang

“…Single-walled carbon-nanotube (SWCNT) arrays are generated on catalyst patterns with controlled location, orientation, and spacing using a straightforward approach. Dip-pen nanolithography is used to fabricate catalyst patterns with sub-70 nm resolution, and SWCNTs are successfully grown on these patterns through chemical vapor deposition. …”

Controlled growth of nano-and bio-arrays on patterned substrates by Zhang, Hua, Li, Bing, Zhou, Xiaozhu, Lu, Gang, Cao, Xiehong, Boey, Freddy Yin Chiang

“…In this talk, we introduce several methods developed in our group to show how to control the growth of bio-and nanoarrays on patterned solid substrates. By using dip-pen nanolithography (DPN), the polyamidoamine (PAMAM) dendrimers were patterned on solid substrates, which were successfully used as templates for controlled growth of peptide nanoarrays. …”
